Description and Details: This is SNR G119.5 +10.2 or also known as CTA1. It is a faint supernova remnant near Cepheus that is estimated to have gone supernova about 10-14k years ago. A faint pulsar in the core is pushing gases outward from its core. It was first estimated to have a pulsar back in 1960 when discovered but nothing was found, not until 2008 was it confirmed to have a faint signal.
NGC40 is the small planetary in this field which is often captured, but the region is full of activity from this Supernova as well, which is not as commonly captured. 40hrs of imaging was captured across HSO filters using a fast F/2.2 RASA astrograph and ASI6200mm camera. Captured from my backyard observatory in Pendleton, Oregon.
